Type Alias GenericCalcAnchorSizeFunction

pub type GenericCalcAnchorSizeFunction<L> = GenericAnchorSizeFunction<Box<GenericCalcNode<L>>>;

anchor-size() function used in math functions.

Aliased Type

struct GenericCalcAnchorSizeFunction<L> {
    pub target_element: DashedIdent,
    pub size: AnchorSizeKeyword,
    pub fallback: Optional<Box<GenericCalcNode<L>>>,
}

Fields

target_element: DashedIdent

Anchor name of the element to anchor to. If omitted (i.e. empty), selects the implicit anchor element.

size: AnchorSizeKeyword

Size of the positioned element, expressed in that of the anchor element. If omitted, defaults to the axis of the property the function is used in.

fallback: Optional<Box<GenericCalcNode<L>>>

Value to use in case the anchor function is invalid.

Implementations

impl GenericAnchorSizeFunction<Box<CalcNode>>

fn parse_in_calc<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, ) -> Result<Self, ParseError<'i>>

impl<LengthPercentage> GenericAnchorSizeFunction<LengthPercentage>

pub fn parse_inner<'i, 't, F>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, f: F, ) -> Result<Self, ParseError<'i>>

where F: FnOnce(&mut Parser<'i, '_>) -> Result<LengthPercentage, ParseError<'i>>,

Parse the inner part of anchor-size(), after the parser has consumed “anchor-size(”.

pub fn resolve<'a>( &'a self, position_property: PositionProperty, ) -> AnchorResolutionResult<'a, LengthPercentage>

Resolve the anchor size function. On failure, return reference to fallback, if exists.

where LengthPercentage: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

impl<LengthPercentage: PartialEq> PartialEq for GenericAnchorSizeFunction<LengthPercentage>

fn eq(&self, other: &GenericAnchorSizeFunction<LengthPercentage>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
